Abstract: A computer cursor control which includes a base having two side ends, a bottom surface and a top surface is disclosed. The bottom surface of the base has a concave side-to-side cross section. This concave cross section is ergonomically shaped to conform to and engagingly rest upon the thigh of a user in a variety of sitting positions with the two side ends extending downward below the top of the thigh-engaging contour. The top surface carries a palmer dome upon which the user's hand rests in its most natural condition and the cursor control and other controls are positioned around and upon surfaces of the palmer dome in locations which enable the most used controls to be accessed by the most dexterous digits.
